Samba version/dialect used for mounts.

Hi,
is there a command in linux to get information about which SAMBA dialect has been used for a mount ?

the smbstatus command doesn't do that. or the mount command.

For instance in Windows 7 you need to use Wireshark, and Windows 8 has a PowerShell tool for it... but I was wondering if Linux has something like Mac(Darwin) has to get the samba version used.

Code:

macbook:~ username$ smbutil statshares -a

==================================================================================================
SHARE                         ATTRIBUTE TYPE                VALUE
==================================================================================================
c$                            
                              SERVER_NAME                   192.168.1.20
                              USER_ID                       600
                              SMB_NEGOTIATE                 AUTO_NEGOTIATE
                              SMB_VERSION                   SMB_2.1
                              SMB_SHARE_TYPE                DISK
                              SIGNING_SUPPORTED             TRUE
                              EXTENDED_SECURITY_SUPPORTED   TRUE
                              LARGE_FILE_SUPPORTED          TRUE
                              FILE_IDS_SUPPORTED            TRUE
                              DFS_SUPPORTED                 TRUE
                              FILE_LEASING_SUPPORTED        TRUE
                              MULTI_CREDIT_SUPPORTED        TRUE

What do you want to know, specifically?

For what? Wireshark is the multi-purpose power tool (some call it a weapen) to dig up just about anything that's going on on the network; don't know about Windows 8. But I still wonder what it is that you need to know.

Not really. Frequently, it's given in the server's identification string. But it's meaningless anyway. Samba uses a standard network protocol that is compatible with both ends (client and server) of Windows' file sharing. For all I know, there is no need to know the Samba version anywhere. Just connect to a share (using the mount option "-t cifs" on Linux, using the "Map Network Drive" on Windows Explorer or the "net use" command at the command line), give the required credentials and you're done. Very similar from Mac OS, I guess, as this is a Unixoid system like Linux.

Depending on the server, the samba version(dialect) used is auto-negotiated.

If my Linux client support SMB2.1 mounts but the server is only SMB1.0 I get anSMB1.0 mount.

I want a tool telling me what SMB version(dialect) is in use for that.

Wireshark can be used to sniff the SMB traffic and get this info out of packet capture

But there's a tool in OSX(showed on the #1 post) and Windows 8 has also now a PowerShell Tool for it.

Code:

Windows PowerShell

PS C:\> Get-SmbConnection

ServerName          ShareName           UserName             Credential           Dialect             NumOpens 
----------          ---------           --------             ----------           -------             -------- 
Contoso-FS1         VMS5                Contoso\Contoso-HV1$ Contoso\Contoso-HV1$ 3.00                1 
Contoso-FS1         VMS5                NT VIRTUAL MACHI...  Contoso\Contoso-HV1$ 3.00                3 
Contoso-FS          VMS1                Contoso\Contoso-HV1$ Contoso\Contoso-HV1$ 3.00                1 
Contoso-FS          VMS1                NT VIRTUAL MACHI...  Contoso\Contoso-HV1$ 3.00                5 
Contoso-SO          VMS3                Contoso\Contoso-HV1$ Contoso\Contoso-HV1$ 3.00                1 
Contoso-SO          VMS3                NT VIRTUAL MACHI...  Contoso\Contoso-HV1$ 3.00                1 
Contoso-SO          VMS3                NT VIRTUAL MACHI...  Contoso\Contoso-HV1$ 3.00                2

So wondering if there's one in Linux as well ? I couldn't find it.
